MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 792,159, dated June 13,1905.

Application filed October 18, 1904. Serial No. 228,909.

To a whom it may concern:

Be it known that I, \VILLIAM L. OMALLEY, a citizen of the United States,residing in the city of Davenport, in the county of Scott and State ofIowa, have invented certain new and useful Improvements in M usic-LeafTurners; and I do hereby declare the following to be a full, clear, andexact description of the invention, which will enable others skilled inthe IQ art to which it appertains to make and use the same.

My invention relates to leaf-turners for music; and one of the objectsis to provide a rack for holding the music which may be read- 5 ily andadjustably attached to any music-rack or piano and easily removedtherefrom and will hold the cover or leaves of the music not in useagainst the rack.

Another object is to provide means for turning each leaf of the music byseparate levers with extension-arms and re-turning all the leaves eitherseparately or together.

For a full and clear understanding of the mode of construction and themanner of oper- 5 ating the same attention is called to the followingspecification, when taken in connection with the drawings accompanyingthe same and forming a part hereof.

Figure 1 is a perspective view of the de- 3 vice, taken from the side onwhich the music rests and set in nearly a perpendicular position. Fig. 2is a plan view of the lever for operating the arm to turn the leaf. Fig.3 is a plan view of the lever shown in Fig. 2 with the extension-armattached and turned to an angle. Fig. 4 is a side view of Fig. 2. Fig. 5is a side View of two lovers and arms and shows another mode ofremovably attaching the device to a piano or music-rack or other 4support. Fig. 6 is a vertical section of one of the feet of the rest.Fig. 7 shows the platform cut away and the base-plate with the leversand the arms of Fig. I removed.

Like letters of reference denote corresponding parts in each of thedrawings.

Referring to the drawings, A designates the body of the turner, whichconsists of a frame B, preferably of wire bent into the form of aparallelogram, with the ends of the wire fastened in a platform or plateD. and a stay 5 plate E, secured to the cross-bar C of the frame and tothe platform D, which also serves as a plate against which the musicrests and against which it is held. There is also secured in theplatform D and through the end of the plate E a bar F, which stands outat a short space from the plate E, and between the rod F and plate E themusic is placed, with the center of the sheet back of the bar F.

For the purpose of removably attaching the turner to a piano or othermusic-holder the ends of the platform D are provided with pins G, set atnearly right angles to the platform I), but preferably near the forwardedge, and these engage the top of a hollow rubber foot 5 H. In thismanner the frame, with the rubbers attached, is set in the base of themusicrest or piano and the air forced from the hollow rubber foot H,which will make them stick fast by suction or air-pressure to the 7 restwithout injuring the same and will hold the turner steadily thereon.Another mode of removably attaching the turner to its support is by aclamp, (shown in Fig. 5,) which preferably consists in rigidly attachingto the base-plate WV a rectangular plate Y and providing the end with athumb-screw 71. If the shape to which it is to be attached be irregular,then the clamp may be made of springsteel or other flexible material.

For the purpose of turning the leaves of the music there is pivotedbeneath the platform D to the base IV a lever I. (Shown in Figs. 2 and3.) This lever is provided with a crescent-shaped slot J and anotherstraight slot K, preferably set at right angles to each other, but whichdo not unite or open into each other. T he slot K may be closed at thetop; but for the purpose of more easily putting the parts together it isleft open. Through 9 the slotJ passes a pin or post L, which is rigidlylixed in the base-plate W, and to the upper end of it is pivotallyattached an arm M. Upon the under side, near the inner end of the arm M,is fastened a pin I, which engages with the slot K, and as the arm isturned the pin moves up and down in the slot K. The lever I is pivotedto the base IV by a pin R, and at base-plate W.

the outer end it is provided with a thumbpiece S. To the outer end ofthe arm M is attached a clasp T, which may consist of two plates t,separated in the rear by a spring, (not shown,) so that the clasp willengage the music; but any other convenient means for grasping the musicmay be attached to the arm M and still be in accordance and harmony withthe device. 7

There may be one or a plurality of the levers I, with theirextension-arms M. I have shown only two. These are substantially alike,with the exception that one of the arms is either cut away or bent outat Q, so that the turning of the arm will not interfere or come incontact with the thumb-piece S of the lever I whilepassing it. are allpivoted between plate D and the baseplate W, and when there are morethan one lever or arm then there is interposed a plate Z, to which theupper lever is pivoted and which is rigidly attached to the post Lat oneend. The lower lever M is pivoted in the If there were several of theselevers, then there should be interposed a plate Z between each one ofthe levers, to which the lever above should be pivoted.

' For the purpose of holding the cover of the music or an unused leaf onthe rack and not allowing it to be turned when the leaves areturnedbackthere is fastened to the top piece 0 of the frame a cord andto the other end of the cord a ball or weight X, which rests upon thecover and holds it against theframe.

The manner of operating my device is substantially as follows: Therubbers H are placed in the proper position on the piano, and the airhaving been exhausted from them they are held by suction orair-pressure. Then the frame A is set, with the pins G engaging the topsof the rubbers, and in this manner the frame is removably held upon thepiano and prevented from slipping or moving in any direction. The musicis then placed between the plate E and the bar F and the clasp T setgrasps the lower or shorter lever by the thumbpiece S and turns it inone direction, and as thelever is pivoted by the pivot-pin R to the,

base-plate W and as the post L passes through the slot J in the lever Iand is rigidly fixed in the base-plate W when the outer end of the leveris turned in onedirection the inner end. in which is the slot J, will beturned in the opposite direction in the arc of a circle, with the post Lin the slot J and the slot oscillating about the post. Further, as thearm M is pivoted to the fixed post L and the pin P is fixed to the arm Mand engages the slot K when the lever is turned it will engage the pin Pin the slot K and force the arm M to one side, and the pin P will travelbackward These levers and armsand forward in the slot K. Thus by turningthe lever I the leaf of music attached to the arm M will be turned inthe direction of the oscillation of the lever, and the post L and thepin R will always remain in the same plane and in the same relation toeach other.

It will be seen that as the distance between the post L and the pin R islonger than the distance between the post L and the pin P it will benecessary to move the lever only a short space to carry the arm M fromside to side. It will also be seen since one of the arms M is bent atQwhen it is turned it will not come in contact withthe thumb-piece S onthe lever I or in any manner interfere with its individual movement.

It is manifest that the details of construction may be changed by amechanic skilled in the art to which it appertains within a wide rangewithout departing from the spirit of my invention.
